We've used a Toyota Prius since the first generation as our car of choice for safely transporting rescue animals for our dog rescue charity. This week we pickup our 2019 Prius Limited which will replace a 2012 Prius. We will keep the back seats permanently down, the back area is for rescue dogs, the front two seats for people. I've noticed with the seats down -- especially since we have a lot of items stored behind the two front seats -- little or no AC creeps up from the floor vents... so I had an idea to try this time... We would like to attach some sort of custom "mini-duct" to redirect AC air blowing from underneath the seats into a duct tube of some sort which would then come up in the center to the level just above the seats when they are folded down, so it would then blow to the back of the car above the folded seats, instead of just at the floor. Before I dive into experimenting, has anyone else ever tried this? Or have any suggestions before we try? Thanks!
